[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a metal one-way valve integrated structure, such as Figure 1-Figure 5 As shown, it includes a front valve body 1, a rear valve body 2 is installed at the lower part of the front valve body 1, the front valve body 1 and the rear valve body 2 are riveted by an elastic cylindrical pin 3, a sealing gasket 4 and a support plate 5 are arranged at the center of the interior of the front valve body 1 and the rear valve body 2, a first O-ring 6 is arranged on the inner side of the lower end of the outer side of the front valve body 1, and a second O-ring 7 is arranged on the outer side of the upper end of the front valve body 1. Through the ingenious combination of the front valve body 1 and the rear valve body 2, and the riveting by the elastic cylindrical pin 3, the integrated design of the valve body is realized. This structure not only simplifies the complex assembly process of the traditional one-way valve, but also improves the overall strength and stability of the valve. The sealing gasket 4 and the support plate 5 arranged in the center of the interior effectively enhance the sealing performance and pressure resistance of the valve. At the same time, the first O-ring 6 on the inner side of the outer side of the lower end of the front valve body 1 and the second O-ring 7 on the outer side of the upper end constitute a double sealing mechanism, which further prevents the leakage of gas or liquid and ensures the reliable operation of the valve under various working conditions. In summary, the metal one-way valve integrated structure of the utility model has the advantages of simple structure, good sealing, stability and reliability.

[0026] In this embodiment, the material of the front valve body 1 and the rear valve body 2 is aluminum alloy, which increases the structural strength and enhances the corrosion resistance.

[0027] Specifically, upper interfaces 11 are provided on both sides of the front valve body 1, lower interfaces 21 are provided on both sides of the rear valve body 2, and both ends of the elastic cylindrical pin 3 are respectively connected to the upper interface 11 and the lower interface 21, so as to facilitate the connection and fixation of the front valve body 1 and the rear valve body 2.

[0028] Furthermore, an annular groove is provided on the upper portion of the front valve body 1 , and the second O-ring 7 is clamped in the annular groove to ensure the sealing performance of the upper connection of the front valve body 1 .

[0029] Furthermore, an annular groove is provided at the lower portion of the front valve body 1 , and the first O-ring 6 is stuck in the annular groove to ensure the sealing performance of the lower connection of the front valve body 1 .

[0030] Furthermore, the elastic cylindrical pin 3 is a circular ring structure, and a vertical notch is provided on one side, so that the elastic cylindrical pin 3 has elasticity and connects and fixes the front valve body 1 and the rear valve body 2 .

[0031] Furthermore, the sealing gasket 4 is provided with a plurality of through holes. The plurality of through holes provided on the sealing gasket 4 not only helps to balance the pressure difference between the inside and outside of the valve, but also plays a role of buffering and shock absorption when the valve is working, thereby further improving the sealing performance and stability of the valve. At the same time, the design of the through holes also helps to reduce the deformation and wear of the sealing gasket 4 caused by uneven force during long-term use, thereby extending the service life of the valve.

[0032] Furthermore, a circular hole is provided in the middle of the support plate 5, a clamping column 12 is installed at the bottom of the front valve body 1 through a fixing rod, a clamping groove 22 is provided inside the rear valve body 2, and the clamping column 12 is clamped and matched with the clamping groove 22 to ensure accurate docking of the front valve body 1 and the rear valve body 2.

[0033] The metal one-way valve integrated structure of the utility model mainly relies on its ingenious structural design and high-quality material selection when in use. When the front valve body 1 and the rear valve body 2 are tightly connected by the elastic cylindrical pin 3, they together form a strong and sealed valve body.

[0034] Specifically, when a fluid (such as gas or liquid) enters from one end of the valve, it will first contact the sealing gasket 4. Due to its excellent sealing performance, the sealing gasket 4 can effectively prevent fluid leakage and ensure that the fluid can pass through the valve smoothly. At the same time, the support plate 5 provides additional support and stability for the valve, so that the valve can maintain its shape and performance when subjected to high pressure.

[0035] Furthermore, the first O-ring 6 on the inner side of the lower end of the front valve body 1 and the second O-ring 7 on the outer side of the upper end form a double sealing mechanism. The two O-rings are respectively stuck in the annular grooves of the front valve body 1, ensuring a tight fit between the valve and the connecting parts, and further preventing leakage of the fluid.

[0036] When the valve is working, the elastic cylindrical pin 3 not only connects the front valve body 1 and the rear valve body 2, but also has a certain elasticity due to its circular ring structure and the vertical notch on one side, which enables the valve to maintain its structural integrity when subjected to pressure or temperature changes.

[0037] In addition, the through holes formed on the sealing gasket 4 also play an important role in the operation of the valve. They not only help to balance the pressure difference between the inside and outside of the valve, but also play a role of buffering and shock absorption when the valve is opened or closed, thereby improving the sealing performance and stability of the valve.

[0038] Finally, the circular hole in the middle of the support plate 5, the clamping column 12 at the bottom of the front valve body 1 and the clamping groove 22 inside the rear valve body 2 together ensure the accurate docking of the front valve body 1 and the rear valve body 2. This design enables the valve to maintain its high precision and stability during assembly and use.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
